Handguns

Beretta 92SB

General Ross, enraged, shoots Hulk several times with what appears to be an olive-colored Beretta 92SB in "What If... The World Lost Its Mightiest Heroes?" (S1E03), but of course, this does not harm him in any way. Sharon Carter is armed with the same gun in "What If... Zombies!?" (S1E05). She uses it when she and Happy stumble upon Zombie Hawkeye and a small crowd of other zombies. During the fight, the pistol is destroyed by a shot from the Iron Man Gauntlet of the Zombie Happy. James Rhodes is armed with a pistol in "What If... Killmonger Rescued Tony Stark?" (S1E06). He pulls out his pistol when the alarm goes up and then shoots the Black Panther several times. T'Challa draws out the pistol, explaining that he will not harm Rhodes.

He takes it out of an invisible holster and holds it while checking abandoned buildings and later, during the final battle with Zombie Scarlet Witch. Black Widow briefly holds a Glock 17 again during the famous Avenger posing scene in "What If... Killmonger Rescued Tony Stark?" (S1E06). Ulysses Klaue also uses the pistol in the same episode. He pulls it out of the holster during the attack on the Churchill ship but immediately hides in the shadows. Black Widow also carries the Glock 17 in "What If... Ultron Won?" (S1E08) and uses it during an Ultron Sentries attack at the HYDRA Siberian Facility. Natasha continues to use her pistol in "What If... The Watcher Broke His Oath?"

First, it is briefly visible on the belt during Ego's Expansion, then T'Challa aims them at Natasha when she stole the Infinity Stone, and after that, the blasters are seen several times during the battle with the Ultron (including when referring to the famous scene with the posing of the Avengers). After defeating Ultron, T'Challa teaches his new friend Peter Quill how to shoot a blaster.

In "What If... T'Challa Became a Star-Lord?" (S1E02) T'Challa points his blaster at the lock...

...and holsters it.

Gabe with his Thompson is seen on the right. Unlike the original film, here he uses a Thompson, not a Browning M1919A4.

Like all Black Widows, Natasha Romanoff has and uses a wrist electroshock weapon called Black Widow's Bite during an Ultron Sentries attack at the HYDRA Siberian Facility in "What If... Ultron Won?"

Hawkeye uses his bow during the Infiltration into the S.H.I.E.L.D. Crater Investigation Site. He holds Thor at gunpoint and suddenly fires. He also uses his bow in "What If... Zombies!?" (S1E05). Hawkeye also briefly uses his bow during the famous Avenger posing scene in "What If... Killmonger Rescued Tony Stark?" (S1E06). Hawkeye uses his bow with different types of arrows (some of which appear for the first time in MCU) as the main weapon in "What If... Ultron Won?" (S1E08). After Hawkeye's death, Natasha takes his bow for herself (in fact, this is rather strange, since the bow had to be destroyed along with the owner) and uses it only once, when she launches an arrow with Zola Virus into Ultron's eye in "What If... The Watcher Broke His Oath?" (S1E09), destroying him.

Zombified Tony Stark uses the Mark L Armor's palm repulsors in a fight with the Black Order, and later with Bruce Banner at the beginning of "What If... Zombies!?" (S1E05).

Some kind of explosive guns are mounted on Stark Liberator Drones created by Stark and Killmonger in "What If... Killmonger Rescued Tony Stark?" (S1E06). The first drone released attacks Killmonger in Stark's apartment without using a cannon. After the death of Tony Stark, Stark Industries workers, together with the US Government, create an entire army of Liberator Drones for the war with Wakanda. During the battle with Dora Milaje, drones actively use cannons.

The barrel of the gun is visible during a fight between the first drone and Killmonger in Tony's apartment. The muzzle resembles the muzzle of a Mk 19 Grenade Launcher.

Another quad wrist-mounted rotary guns are seen during the landing of Drones army in Wakanda.

Trivia

Panzerkampfwagen VI "Tiger"

The HYDRA uses a variety of heavy Tiger tanks throughout "What If... Captain Carter Were The First Avenger?" (S1E01).

A few heavy Tiger tanks attack Captain Carter and Howling Commandos, but HYDRA Stomper destroys it. Carter also destroys one, damaging the tracks.
